Test creation of [VDJ]Smooshables

  VGermline vgerm_obj(V_root);
  DGermline dgerm_obj(D_root);
  JGermline jgerm_obj(J_root);

  Smooshable VSmoosh = VSmooshable(vgerm_obj, std::make_pair(0,2),
                                   std::make_pair(5,7), emission_indices, 2);

  Smooshable DXSmoosh, DNSmoosh;
  std::tie(DXSmoosh, DNSmoosh) = DSmooshables(dgerm_obj, std::make_pair(4,5),
                                              std::make_pair(6,8), std::make_pair(10,11),
                                              emission_indices, 5);

  Smooshable JXSmoosh, JNSmoosh;
  std::tie(JXSmoosh, JNSmoosh) = JSmooshables(jgerm_obj, std::make_pair(5,6),
                                              std::make_pair(8, 9), std::make_pair(12, 13),
                                              emission_indices, 8);

Can we test the creation of these Smooshables?
